Desertification is the degradation of formerly productive land. It occurs all over the world but is only referred to as desertification when it takes place in dry lands. This involves the depletion of vegetation and soils. Desertification has always been around: the world’s greatest deserts were formed by natural processes interacting over long intervals of time. There are many arguments over the cause of desertification. They include climate change, human activities, clearing and cultivation of low-rainfall areas, and drought. This has a huge impact on the people and the environment.
